This figure shows the rate of change of the ‘water balance’.
The map provides an estimate increase (red in map) or decrease (blue in map) of the volume of water required from irrigation assuming that all other factors are unchanged and given that there is an irrigation demand.

The figure shows the simulated change in water-limited wheat production for 2030 compared with 2000 for the A1B emission scenario using a cold (ECHAM5) (left) and a warm (HADCM3) (right) climate change projection.
The simulation was performed on a 25x25 km grid (assuming current area of wheat cropping) but the results are presented here at the NUTS-2 level.

The map shows the volume of irrigated water used (in m³) for potatoes per production value at producer price (values at current prices) in € PPS among different countries in Europe at NUTS2 level.
In cases where NUTS2 level data was not available the map shows the result in country level.

The chart displays changes in emission of phosphorus from agriculture (expressed as phosphorus balance, P-balance) , and the economic output of agriculture and related services and activities expressed as the gross value added (GVA) in Europe between 2000 and 2008. Changes are expressed in %, where values for 2000=100 %.

This figure shows the rate of change of the flowering date for winter wheat. The flowering date is defined as the day at which a modelization of the winter wheat reaches a development state of 100 in a scale 0 - 200 defined for the WOFOST growth model (Van Keulen H, Wolf J (1986) Modelling of agricultural production: weather soils and crops, Simulation monographs. Pudoc, Wageningen). The map shows the yearly change rate in days per year calculated for the period January 1975 - December 2010.

Many developing country economies are centred on exploiting natural resources to lift their populations out of poverty, potentially damaging the natural systems they depend on. Short-term solutions often undermine the population’s well-being in the long-term. Can governments help the markets set the ‘right’ price for nature’s services and influence economic choices? Here is a closer look at what water use in cotton production means for Burkina Faso.
